Video4Linux backend patching

[jb892]

System Configuration

Please complete Your Configuration detail below. Refer to the BKC at Configuration.

Version	Your Configuration
Operating System	Ubuntu 16.04 LTS
Kernel	4.4.0-040400-generic
Backend
ROS	kinetic
ROS RealSense	Cannot locate [realsense_camera]
librealsense	0.9.1
R200 Firmware	1.0.72.06

When I run the example program "cpp-capture", it only can last for 2 seconds and then it crashes. So, I suspect that maybe my Video4Linux backend isn't installed correctly. Then, I tried several times to reinstall the backend and all attempts seem failed.

Patching command:
$ ./scripts/patch-uvcvideo-16.04.simple.sh
After I reloaded the uvcvideo. I have some errors:

$ sudo dmesg | tail -n 50

I have reported this issue to IntalRealsense community. However, 5 days passed and nobody reply me. Could you please help me to solve this issue? Thanks!

Hi @jb892 filing the issue at librealsense is the right place to resolve this. We have not encountered this issue on the ROS side, and I would recommend you review the installation docs at librealsense here: https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md
